Background

Put red, green and blue into the RGB fields. The hex code appears in the field above, ready for a stylesheet, with HSL and CMYK alongside.

RGB is what most design apps show; hex is what most stylesheets carry.

Keep the RGB values if the file you are writing needs them later.
HSL sits on the same panel, which is where lightness is easiest to read.
